HMIT, SMIT, and TAUT are downregulated 72‐hr following exposure to acute‐solar simulated radiation (SSR) in vivo. Immunofluorescence for HMIT, SMIT, and TAUT was conducted in healthy photoprotected skin following acute irradiation (80 mJ) with solar simulated radiation (SSR) at (a, f, k) baseline (unirradiated control) and (b, g, l) 1‐hr, (c, h, m) 3 hr and (d, i, n) 72 hr following SSR exposure. Protein expression was significantly downregulated at 72‐hr post‐SSR for (e) HMIT (p = .0015), (j) SMIT (p = .0104), and (o) TAUT (p = .0054). Data expressed as mean ± SD (one‐way ANOVA), n = 5. Scale bars = 20µm. HMIT, hydrogen‐coupled myoinositol transporter; SMIT, sodium‐coupled myoinositol transporter; TAUT, taurine transporter
